FIG. 2 is a structure diagram of a second magnetic adhering structure according to an embodiment of the present disclosure. Referring to FIG. 2 , in an embodiment, the second magnetic adhering structure 30 and the display panel 20 have a same size. In this way, the knob 10 can be freely adhered to any position of the display panel 20, and any adhering position of the knob 10 corresponds to one first magnetic adhering region MA.

Specifically, the second magnetic adhering structure 30 is an entire surface structure. That the second magnetic adhering structure 30 and the display panel 20 have the same size refers to that an error between the second magnetic adhering structure 30 and the display panel 20 is within a preset tolerance, and a specific value of the preset tolerance can be set by a person skilled in the art according to the practical situation. The display device may further include a first housing disposed on a non-light exiting side of the display panel 20, and the second magnetic adhering structure 30 with the entire surface structure may be disposed on the first housing. The second magnetic adhering structure 30 may be an energized coil, and is fixed on the first housing by gluing. The second magnetic adhering structure 30 may also be a magnet, and is fixed on the first housing by gluing or a buckling structure on the first housing. It should be understood that, because the second magnetic adhering structure 30 is an entire surface structure, the entire second magnetic adhering structure 30 can be laid without aligning, so that the second magnetic adhering structure 30 can easily be assembled. Moreover, the requirement on precision of the size of the second magnetic adhering structure 30 is relatively low, so that precision of a preparation process of the second magnetic adhering structure 30 is low, which is conductive to reducing the difficulty in preparation of the second magnetic adhering structure 30.

It should be noted that the second magnetic adhering structure 30 shown in FIG. 2 actually includes a plurality of first magnetic adhering regions MA. However, since it is difficult to divide all of the plurality of first magnetic adhering regions MA, only three first magnetic adhering regions MA are shown exemplarily in FIG. 2 .

FIG. 3 is a structure diagram of another second magnetic adhering structure according to an embodiment of the present disclosure. FIG. 4 is a structure diagram of still another second magnetic adhering structure according to an embodiment of the present disclosure. Referring to FIG. 3 and FIG. 4 , in an embodiment, the second magnetic adhering structure 30 includes a plurality of second magnetic adhering pieces 31, and any two of the plurality of second magnetic adhering pieces 31 are disposed at different positions. Specifically, each second magnetic adhering piece 31 corresponds to a first magnetic adhering region MA. The specific shape and structure of the second magnetic adhering piece 31 can be set by those skilled in this art according to the practical situations, and is not limited herein. Exemplarily, the second magnetic adhering piece 31 can be an integral structure and can have a shape of circle (as shown in FIG. 3 ), ring, rectangle, or the like. Exemplarily, the second magnetic adhering piece 31 further includes a plurality of second magnets 311, the plurality of second magnets 311 may be arranged regularly, for example, the plurality of second magnets are arranged in a straight line shape, a broken line shape, a wave shape or a ring shape (as shown in FIG. 3 ); the plurality of second magnets 311 may also be irregularly arranged. It should be noted that FIG. 3 and FIG. 4 only exemplarily show the regular arrangement of the plurality of second magnetic adhering pieces 31, but it is not a limitation of the present application. In other embodiments, the plurality of second magnetic adhering pieces 31 may also be irregularly arranged. When the plurality of second magnetic adhering pieces 31 is regularly arranged, the plurality of second magnetic adhering pieces 31 may be arranged in a matrix (as shown in FIG. 3 and FIG. 4 ), a rectangular-ambulatory-plane shape, a spiral shape, a bow shape, or other manners known by those skilled in the art.

It should be understood that the second magnetic adhering structure 30 includes a plurality of second magnetic adhering pieces 31, so that those skilled in the art can flexibly set the number of the second magnetic adhering pieces 31 in the second magnetic adhering structure 30, the area of each second magnetic adhering piece 31, the arrangement manner of the plurality of second magnetic adhering pieces 31, and the distance between adjacent second magnetic adhering pieces 31. Moreover, by adjusting the number and distribution density of the second magnetic adhering pieces 31, the cost of the second magnetic adhering structure 30 can be flexibly adjusted. It should also be understood that the size of each second magnetic adhering piece 31 is relatively small, and the magnetic adhering force generated by the second magnetic adhering piece 31 is relatively small, which can prevent an external paramagnetic component of a large size from being mistakenly adhered to the display panel 20.

FIG. 5 is a structure diagram of yet another second magnetic adhering structure according to an embodiment of the present disclosure. Referring to FIG. 5 , in an embodiment, the display panel 20 includes a central region CA and an edge region WA surrounding the central region CA, and a distribution density of second magnetic adhering pieces 31 in the central region CA is smaller than a distribution density of second magnetic adhering pieces 31 in the edge region WA; and a ratio of an area of the central region CA to an area of the edge region WA has a range from 2:1 to 3:1

It should be understood that an object currently controlled by the knob 10 usually matches a content currently displayed on the display panel 20. For example, when the display panel 20 displays a parameter setting interface of an air conditioner, the user can rotate the knob 10 to adjust parameters, such as the temperature, the running manner. Therefore, in order to prevent the knob 10 from blocking the display content of the display panel 20, the user has a greater chance of choosing to adhere the knob 10 to a corner of the display panel 20. It should be understood that the distribution density of the second magnetic adhering pieces 31 in the edge region WA is relatively large, which can make a distribution density of the first magnetic adhering regions MA in the edge region WA larger, which is convenient for the user to find and operate the knob 10 and does not affect the adhering position of the knob 10 displayed on the display panel 20.

FIG. 6 is a structure diagram illustrating a first magnetic adhering piece and a second magnetic adhering piece adhered to each other according to an embodiment of the present disclosure. In an embodiment, when the second magnetic adhering structure 30 includes a plurality of second magnetic adhering pieces 31, the first magnetic adhering piece 11 and the second magnetic adhering piece 31 have a same shape, and a difference between a size of the first magnetic adhering piece 11 and a size of the second magnetic adhering piece 31 is smaller than a second preset tolerance; a specific value of the second preset tolerance can be set by those skilled in the art according to the practical situations, and is not limited herein. It should be noted that, in order to clearly illustrate the first magnetic adhering piece 11 and the second adhering piece 31, the display panel 20 is not shown in FIG. 6 , but actually, at least the display panel 20 is spaced between the first magnetic adhering piece 11 and the second adhering piece 31, and additionally, FIG. 6 exemplarily shows that the first magnetic adhering piece 11 and the second adhering piece 31 have a same shape and a same size.

It should be understood that when the knob 10 is adhered to the display panel 20, an orthographic projection of a first magnetic adhering piece 11 on the display panel 20 almost coincides an orthographic projection of a second magnetic adhering piece 31 (referred to as an active second magnetic adhering piece 31) adhered to the first magnetic adhering piece 11 on the display panel 20, and a magnetic force applied by the active second magnetic adhering piece 31 on the first magnetic adhering piece 11 is almost perpendicular to the display panel 20, so that the magnetic force generated by the active second magnetic adhering piece 31 is almost used for adhering the first magnetic adhering piece 11, thereby making an active utilization rate of the magnetic force generated by the active second magnetic adhering piece 31 higher.

FIG. 7 is a structure diagram of another display device according to an embodiment of the present disclosure. Referring to FIG. 7 , in an embodiment, the display panel 20 includes a liquid crystal display panel, the display device further includes a backlight module 40, and the second magnetic adhering structure 30 is disposed on a backplane 41 of the backlight module 40.

Specifically, the liquid crystal display panel includes an array substrate 21, a color filter substrate 23, and a liquid crystal layer 22 disposed between the array substrate 21 and the color filter substrate 23; the liquid crystal display panel does not emit light and needs the backlight module 40 to provide a light source. The specific structure of the backlight module 40 may be set by those skilled in the art according to the practical situations, and is not limited herein. Exemplarily, with continued reference to FIG. 7 , the backlight module 40 includes a backplane 41, a light emitting element 42, and an optical film assembly; the optical film assembly includes a reflection sheet 43, a light guide plate 44, a first diffusion sheet 45, a first prism sheet 46, a second prism sheet 47, and a second diffusion sheet 48, which are stacked in turn; the light emitting element 42 is disposed on a side face of the light guide plate 44, and the backplane 41 is used for accommodating and protecting the light emitting element 42 and the optical film assembly. In an embodiment, the second magnetic adhering structure 30 may be fixedly disposed on a surface of a side of the backplane 41 away from the liquid crystal display panel by bonding, welding or other manners known to those skilled in the art. Thus, the second magnetic adhering structure 30 does not affect other devices in the backlight module 40, and at the same time, avoids blocking a light path of the display device, and ensures a high-quality light source emitted by the backlight module 40.

It can be understood that, compared with the provision of a separate substrate for carrying the second magnetic adhering structure 30, reusing the backplane 41 to carry the second magnetic adhering structure 30 is conductive to implementing lightening and thinning of the display device.

FIG. 8 is a structure diagram of still another display device according to an embodiment of the present disclosure. Referring to FIG. 8 , in an embodiment, the display panel 20 includes an organic light emitting display panel; the display device includes a first housing 51, the first housing 51 is disposed on a non-light exiting side of the organic light emitting display panel, and the second magnetic adhering structure 30 is disposed on the first housing 51.

In an embodiment, the second magnetic adhering structure 30 may be fixedly disposed on the first housing 51 by bonding, welding or other manners known to those skilled in the art. It can be understood that, compared with the provision of a separate substrate for carrying the second magnetic adhering structure 30, reusing the first housing 51 to carry the second magnetic adhering structure 30 is conductive to implementing the lightening and thinning of the display device.

With continued to reference to FIG. 8 , in an embodiment, the second magnetic adhering structure 30 may be disposed on a surface of a side of the first housing 51 facing towards the display panel 20. Therefore, the second magnetic adhering structure 30 can be wrapped in the display device, and the adhering capability of the second magnetic adhering structure 30 to outside paramagnetic substance is reduced. In an embodiment, a support structure may be further disposed between the second magnetic adhering structure 30 and the display panel 20, and the support structure is used for supporting the display panel 20, so as to prevent the second magnetic adhering structure 30 from directly contacting the display panel 20, and prevent the second magnetic adhering structure 30 with an uneven surface from damaging the display panel. Exemplarily, the support structure may be a form gel.

In an embodiment, the second magnetic adhering structure 30 may be disposed on a surface of a side of the first housing 51 away from the display panel 20. It should be understood that, a printed circuit board is usually disposed in the display device, a magnetic element such as an inductor is usually disposed on the printed circuit board, and the second magnetic adhering structure 30 is disposed on a side of the first housing 51 away from the display panel 20, so that a distance between the second magnetic adhering structure 30 and the magnetic element can be increased, thereby reducing interference of the second magnetic adhering structure 30 on the magnetic element.

FIG. 9 is an exploded view of a knob according to an embodiment of the present disclosure. FIG. 10 is a schematic diagram illustrating a relative position relationship between a first charging coil and a second charging coil when a knob is adhered to a first charging region 33 according to an embodiment of the present disclosure. FIG. 11 is a schematic diagram illustrating another relative position relationship between a first charging coil and a second charging coil when a knob is adhered to a first charging region 33 according to an embodiment of the present disclosure. FIG. 12 is a schematic diagram illustrating still another relative position relationship between a first charging coil and a second charging coil when a knob is adhered to a first charging region 33 according to an embodiment of the present disclosure. Referring to FIG. 9 to FIG. 12 , in an embodiment, the knob 10 further includes a first charging coil 12 and a battery 13, and the battery is electrically connected to the first charging coil 12; the display device further includes at least one second charging coil 60; and the plurality of first magnetic adhering regions MA includes at least one first charging region 33; when the knob 10 is magnetically adhered to the first charging region 33, an orthographic projection of the first charging coil 12 on the display panel 20 at least partially overlaps an orthographic projection of the second charging coil 60 on the display panel 20.

Exemplarily, referring to FIG. 9 , the knob 10 includes a first housing 191 and a second housing 192, the battery 13 and the first charging coil 12 are disposed in the accommodation space formed by the first housing 191 and the second housing 192, the second housing 192 is reused as the first magnetic adhering piece 11. When the knob 10 is adhered to the display panel 20, the second housing 192 is in contact with the display panel 20. Specifically, the exact component powered by the battery 13 in the knob 10 is not described here, and will be described in detail below.

Specifically, when the knob 10 is adhered to the first charging region 33, the second charging coil 60 can charge the battery 13 through the first charging coil 12 with following principle: when an alternating current flows in the second charging coil 60, the second charging coil 60 can generate a changing magnetic field, the first charging coil 12 is located in the changing magnetic field, and a current with a corresponding magnitude can be generated according to the changing magnetic field to charge the battery 13.

In an embodiment, with continued reference to FIG. 9 , the first charging coil 12 is disposed on a surface of a side of the second housing 192 away from the display panel 20, so that, along a direction perpendicular to the display panel 20, a distance between the first charging coil 12 and the second charging coil 60 can be made as short as possible, thereby increasing charging efficiency.

With continued reference to FIG. 10 to FIG. 12 , in an embodiment, when the knob 10 is magnetically adhered to the first charging region 33, an orthographic projection of the first charging coil 12 on the display panel 20 and an orthographic projection of the second charging coil 60 on the display panel 20 overlap, so that when the alternating current in the second charging coil 60 is constant, the current generated by the first charging coil 12 can be made as large as possible, thereby increasing the charging efficiency.

Referring to FIG. 11 and FIG. 12 , in an embodiment, the second magnetic adhering structure 30 includes a plurality of second magnetic adhering pieces 31, and any two second magnetic adhering pieces 31 are disposed at different positions; when the knob 10 is magnetically adhered to the first charging region 33, a second magnetic adhering piece 31 to which the first magnetic adhering piece 11 is magnetically adhered is an active second magnetic adhering piece 31Y, and a second charging coil 60 for charging the battery 13 is an active second charging coil 60Y; and a relative position relationship of the active second magnetic adhering piece 31Y and the active second charging coil 60Y is the same as a relative position relationship of the first magnetic adhering piece 11 and the first charging coil 12.

The relative position relationships being the same refers to that, when the knob 10 is magnetically adhered to the first charging region, the orthographic projection of the first magnetic adhering piece 11 on the display panel 20 and the orthographic projection of the active second magnetic adhering piece 31Y on the display panel 20 coincide, and at the same time, the orthographic projection of the first charging coil 12 on the display panel 20 and the orthographic projection of the second charging coil 60 on the display panel 20 coincide. This ensures that the knob 10 is located in the first charging region 33 when the knob 10 is adhered, thereby implementing the efficient charging.

It should be understood that the number and distribution of the first charging regions 33 are related to the number and distribution (distribution in a horizontal plane parallel to the display panel 20) of the second charging coils 60, and may be set by those skilled in the art according to practical situations, and is not limited herein.

In an embodiment, when the distance between two adjacent first charging regions 33 is greater than the first preset distance, the first charging regions 33 correspond to the second charging coils 60 one by one, as shown in FIG. 11 and FIG. 12 . In this way, the conditions that the positional relationship between the first charging regions 33 and the second charging coils 60 corresponding thereto needs to satisfy is relatively loose, the arrangement manner of the positional relationship between them is diversified, and those skilled in the art can arrange the first charging regions 33 and the second charging coils 60 corresponding thereto at suitable positions according to the practical situations. It should be noted that, the specific value of the first preset distance may be set by those skilled in the art according to practical situations, and is not limited herein.

In an embodiment, when the distance between two adjacent first charging regions 33 is smaller than the second preset distance, at least two first charging regions 33 share one second charging coil 60. Exemplarily, FIG. 13 is a structure diagram of a second charging coil shared by two first charging regions according to an embodiment of the present disclosure. Referring to FIG. 13 , the first charging region 33 a includes two first sub-charging regions 331 a. When the first magnetic adhering piece 12 in the knob 10 is adhered to the first charging region 33 a, the second charging coil 60 can charge the battery 13 through the first charging coil 14. At the same time, the first charging region 33 b includes two first sub-charging regions 331 b. When the first magnetic adhering piece 12 in the knob 10 is adhered to the first charging region 33 b, the second charging coil 60 can charge the battery 13 through the first charging coil 14 as well. It should be understood that when at least two first charging regions 33 share one second charging coil 60, more first charging regions 33 can be obtained by providing less second charging coils 60, that is, more optional first charging regions 33 are provided with less cost. It should be noted that, the specific value of the second preset distance may be set by those skilled in the art according to practical situations, and is not limited herein.

Specifically, along the direction perpendicular to the display panel 20, there are many specific locations for disposing the second charging coil 60. According to whether the second charging coil 60 is integrated in the display panel 20, the second charging coil 60 can be divided into two types. Typical examples are described below, but are not limited to the present application.

In a first type, the second charging coil 60 is integrated in the display panel 20.

FIG. 14 is a structure diagram of a display panel according to an embodiment of the present disclosure. FIG. 15 is a cross-sectional view taken along a line AA′ in FIG. 13 . Referring to FIG. 14 and FIG. 15 , in an embodiment, the display panel 20 includes a substrate 20 and a plurality of metal layers 210 disposed on the substrate 20; an insulating layer JY is disposed between adjacent metal layers for insulation; and the second charging coil 60 is disposed in a same layer as one of the plurality of metal layers.

Specifically, the second charging coil 60 may be disposed in a same layer as the gate metal layer 211, as shown in FIG. 11 ; the second charging coil 60 may also be disposed in a same layer as the source-drain metal layer 212. Here, disposing in a same layer refers to forming in a same preparation process.

It should be understood that by forming the second charging coil 60 and one of the plurality of metal layers in the same preparation process, a step of separately preparing the second charging coil 60 can be omitted, which is conducive to reducing cost. Moreover, the second charging coil 60 is integrated into the display panel 20, a process step of fixing the second charging coil 60 can be omitted, and the assembly efficiency of the display device is increased.
